If Openser is in the same LAN as the UA, then no rtp proxy should be utilized.   Could someone please help me out to configure rtp proxy correctly?

Compare source IP of the request ($si during INVITE processing) with the source IP of each response ($si during ON_REPLY_ROUTE). But is very important:

• You must store INVITE source IP in an AVP and set: modparam("tm", "onreply_avp_mode", 1)

and them compare the AVP with the $si in ON_REPLY_ROUTE, and only apply RtpProxy if they don't match.

I've it working perfectly.

BTW **REMEMBER** that you must fix NAT for SIP signallig even if both users are behind the same NAT router since requests, responses and in-dialogs request must be routed through the proxy.
